COLLAR SHAPING AND EDGING MACHINE.

Specification of Letters Patent.

Patented Mar. 28, 1911.

Application filed June 27, 1910. Serial No. 569,038.

To all whom it may concern:

Be it known that I, JOHN J. POLASKI, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Collar Shaping and Edging Machines, of which the following is a full, clear, and precise specification.

My invention relates to laundry machinery, particularly to collar shaping and edging machines.

Among the important objects of my invention are to provide a machine which can be used with equal facility and efliciency for treating either turn-down or stand-up collars; to provide a machine of this class with an entrance edging surface and an exit edging surface whereby the collar edge receives a final edging treatment after its first edging treatment and its passage between the shaping rolls and guides; to provide improved construction and arrangement for the propulsion and shaping rolls and mechanism; to provide improved means for supplying heat to the edging surfaces, particularly to provide for electrically heating such surfaces; to provide improved resilient mounting for one of the shaping rolls and improved construction of the driving mechanism therefor; to construct a machine possessing the above characteristics with a minimum number of parts to reduce the size and weight of the machine and to simplify the operation thereof; and in general to provide a more useful and efficient machine of the class referred to.

The nature of my invention will be plainly understood from the following specification and the accompanying drawings, in which drawings- Figure 1 is a plan view of the machine, Fig. 2 is a front elevation thereof, Fig. 3 is an enlarged sectional view taken on line 33, Fig. 1 to show particularly the edging and shaping mechanism, Fig. 4 is a view taken substantially on line 44, Fig. 3 to show a modified electrical heating arrangement, and Fig. 5 is a sectional view taken on plane 55, Fig. 1.

The machine frame comprises vertical end frames 1 and 2 connected together by side frames or braces 3 and 4. Bearing lugs 5 and 6 extend laterally from the upper end of the side frame 2 and journal a drive shaft 7 loosely pivoting at its outer end a drive pulley 8 adapted for driving connection with the shaft by suitable clutch mechanism 9 controlled by the disk 10. This drive shaft between the bearings 5 and 6 mounts a worm 11 which meshes with a worm wheel 12 carried at the end of the roll shaft 13, a h0using 14 secured to the bearing lugs serving to protect the worm and worm wheel. The other end of shaft 13carries a transmission gear 14 meshing with transmission pinion 15 at the end of shaft 16 running parallel to shaft 13. The side frames 1 and 2 have on their tops rectangular extensions 17 and 18 forming transverse rectangular pockets 19 and 20 for receiving the bearing blocks 21, 22 and 23, 24 for shafts 16 and 13 respectively. The blocks 21 and 22 are fixed in the slots by means of upper and lower pivotal set screws 25 and 26 respectively so that these blocks form pivotal bearings for the shaft 16 but to fix the shaft 16 against trans verse play. The blocks 23, 24 for shaft 13 are, however, slidable in their slots, their pivotal set screws 27 extending into slots 28 in said blocks to pivotally set said blocks in the slots but to allow longitudinal movement therein to carry the shaft 13 from or toward shaft 16 as best shown in Fig. 5. At the driving end of the machine a compression spring 29 carried on set screw 30 abuts against the driving end block and tends to force it toward adjacent block 22 of shaft 16, but the approach of the shaft 13 toward the shaft 16 is limited by a set screw 31 having a tapered end 32 engaging in the crotch 33 of a lug 34 on the driving end block 24 (Fig. 5). By raising and lowering this set screw 31 the distance between shafts 13 and 16 at the driving end can be adjusted. At the transmission end a spring 35 carried on set screw 36 abuts against the block 23, but the distance between the shafts is controlled by a set screw 31 cooperating with the block in the same manner as the set screw 31 coiiperates with the driving end block 24.

Between its bearing blocks the shaft 13 mounts a large roll or drum 38 which may be hollow, as shown in Fig. 3, this drum cooperating with the shaft 16 to propel collars through the machine and to shape them. The section 16 of shaft 16 adjacent the drum is preferably slightly grooved or serrated in order to more efliciently propel the collars. Encircling shaft 16 adjacent the right end of the roll 38 is a heating iron or block 39 secured to flange 40 supported from the machine frame 2 by arms 41, this heating or ironing block, as shown in Figs. 1, 2 and 3, having a flame pocket 42 formed by the upwardly extending wall 43, a burner end 44 being pivotally connected at 45 to a gas supply pipe 46 mounted 011 the frame 2 to be adjustable to deflect the heating flame into the pocket 42. From the inner end of the heating iron or block 39 a guiding and edging block 47 extends forwardly and slightly downwardly and has the *U-shaped guiding and edging groove 48 which flares considerably at its front end and tapers gradually toward its rear end, as best shown in Figs. 2 and 3. Secured to and extending toward the left from the extension 47 are the upper and lower guide plates 49 and 50 whose left ends are secured together by screws 51 and clamp between them an intermediate guide plate or tongue 52 which extends toward the right to within a short distance of the edging groove 48, the end of the tongue being well rounded. The tongue with the upper and lower plates 49 and 50 forms the upper and lower compartments or passageways 53 and 54 through which a turn-down collar is guided into position between the roll 38 and shaft section 16. At the upper part of the inner end of the heating block 39 is cut a groove 55 which forms the exit edging surface 56, and secured to the heating iron over this groove and extending toward the left therefrom is the guide wing or plate 57 for receiving the collar after passage between roll 38 and shaft section 16 to guide the collar forwardly out of the machine and to guide its edge against the finishing surface 56.

At the top of the side frame 1 a lug 58 detachably supports a post 59 whose upper end is surrounded by a water cup 60 for supporting a spool 61 carrying a wick 62.

The operation of the machine can now readily be understood. The clutch is drawn in and the machine started, rotation of the drive wheel being communicated to the shafts 13 and 16 to cause rotation thereof in the direction of the arrows indicated. A turn-down collar which has been previously ironed in its open fiat condition is first run through a seam dampener (which forms no part of this invention) and one end of the collar turned over. The collar is then fed into the machine by inserting the inner and outer bands thereof into compartments 53 and 54 until the inserted end of the collar is taken hold of by the roll 38 and shaft sec tion 16, the end of tongue 52 guiding and holding the seam or edge of the collar against the edging surface 48. hen the collar end reaches the guide wing 57 it is deflected outwardly with its edge or band into groove 55 and against the finishing and edging surface 56, the iron block and its edging extension 48 having, of course, been brought to a sutlicient heat before the collar was inserted, this heat being more or less distributed over the parts to thoroughly dry the collar and to put the proper ironing finish along the band or upper edge thereof. The collar is eventually delivered from the machine, and if it is desired to again subject it to an edging treatment the edge thereof can be run across-the wick 62 to be moistened and the collar then re-inserted into and )assed throu h the machine.

The machine can be used with equal facility for finishing an edge of a stand-up collar, and in order to guide and hold the collar edge against the edging surfaces I provide an attachment for the machine. This attachment comprises a substantially V-shaped guide frame (33 having a supporting stud 64 adjustably supported by set screw 65 along the front end of a rod 66 whose rear end pivots in a lug 67 on the cross frame 4 of the machine to adapt the rod for lateral swing to carry the guiding member 63 toward and away from the edging extension 48, the guide surface 63 for the member 63 being in line with the upper feed compartment 53. The rod 66 carries near its pivoted end an eye extension 68 for detachably receiving one end of a contractile spring 69 which is anchored to the cross frame 4 at 7 0. hen the machine is used for turn-down collars the rod 66 is swung to the left into locking engagement with the latch bar 70 extending from side frame 1 (Fig. 2). However, when stand-up collars are to be treated the spring is connected with the arm so that the guide member is drawn toward the edging block 48. A stand-up collar, after first having its upper edge moistened by passage over the wick 62, is inserted into compartment 53 and between the guide member 63 and edging block 48 until it is taken hold of by the rolls whereupon the collar will be drawn through the rolls and deflected outwardly by the guide wing 57 the guide member 63 and the guide wing 57 serving to hold the collar edge against the inlet and exit edging surfaces. The inward movement of the guiding member 63 can be limited by a stop plate 71 secured to and extending from the edging block 48 to abut against the arm 66. Thus the machine can be used with equal facility for both turn-down and stand -up collars. The ironing block, with its attachments, and the roll members and collar guide members are made from material which is highly conductive to heat so that the heat from the burner will be conducted to the various parts and particularly 1 been described. On passage of a collar through the machine the springs 29 and 35 yield, and thus the collar will not be injured by passage between the rolls, the pressure of the roll 38 against shaft section 16 being suflicient only to insure proper propulsion "of the collar through the machine.

Instead of using a fiame for heating the apparatus electricity can be used as a heat source. As shown in Fig. 4:, the heating head or iron 39 could be heated by means of aheat coil 72 which may be applied in any suitable manner. As shown, the head 39 has an extension 7 3 encircling shaft 16 having the annular pocket 74 for receiving the heat coil or winding 72. A circuit 0 will serve to connect the winding with any suit able source of current, and if desired, a resistance adjusting device R- can be included in the circuit for adjusting the current flow to give desired degrees of heat.

Other changes and modifications may also be made which would still come within the scope of my invention, and I do not, there fore, desire to be limited to the exact forms, construction and operation shown, but
